Dresden was a pleasant-faced and handsome European-looking man with dark hair, graying slightly at the temples, in an expensive haircut. He was tall, giving him a Belter look, but with a solid build like a man in full gravity.

He was the architect of the Eros incident, and theorized by Miller to be a sociopath. Dresden underwent a medical procedure common to all Protogen researchers where parts of their brain were permanently altered to induce extreme sociopathy in an effort to accelerate progress in their experiments on the protomolecule.

After the OPA boarded Thoth Station, where Dresden was overseeing the results of the Eros incident, Miller shot and killed him.
